End cable tap box (Figure 27)
End cable tap boxes are used to feed a run of busway with cable
and conduit or where loads served by busway are connected
without the need for overcurrent protection. For indoor applications,
the “T” side, side opposite “T,” and the end panel are removable
for access to the lugs. For outdoor applications, these panels are
gasketed to prevent moisture from entering. In addition, the
outdoor end cable tap boxes are provided with removable gasketed
side access panels located on the “F” and side opposite “F” for
more accessibility to the lugs. Removable side access panels are
available on indoor cable tap boxes upon request.
ote:N All dimensions are to the centerline of the Pow-R-Bridge.
